Car starts fine in the morning! But then...

During the day when i go to start it again it takes a while before it turns over. Even after it has sat for 3 hours to cool down the engine, its still hard to get it to start. But the next morning it started up again easily. I'm confused.

Ya i figured it was a fuel problem just need to narrow it down, going to check on the PSI in the morning when it starts up right away and after the fact to compare the numbers, well now at least i know it's not due to leaky injectors since they're all new!... Get back to you guys soon with some info.

Fuel Pressure in morning after i primed the pump ~38
While running it stays at 38 with a little needle bounce
Go to start it up again, when it starts up rough and the pressure still holds around the same area...

Edit:

Two more bits of information:

The gauge goes down to zero after night, but still starts right up.

WIth the gauge connected the car NOW starts throughout the day, but i was missing the schrader valve cap so maybe that had something to do with it? Going to have to find another one now cuz i think that has something to do w/ it.
